BTR is the debut studio album by pop boyband Big Time Rush. Released on October 11, 2010, the track listing for the album was announced on September 1, 2010. The album was preceded by the release of several promotional singles, including their self-titled debut single, Big Time Rush. Other promotional songs include "Any Kind of Guy", "City Is Ours", and "Halfway There", which charted on the Billboard Hot 100 singles chart in the US. On September 21, the band released yet another promotional single, titled "Til I Forget About You". It was the last song to precede the album's release of October 11, 2010. "Boyfriend", which features vocals from rapper Snoop Dogg, was the first official single from the album and has become the band's biggest hit to date, charting on the Billboard Hot 100 as well as reaching the Top 40 of the Pop Songs music chart in the US. Despite not being released as a single, the song "Big Night" also charted on the Billboard Hot 100, where it also reached a peak of seventy-nine.

BTR had been in the making since 2009, when the four members signed on for the show, Big Time Rush. The boys worked with composers and producers such as Emanuel Kiriakou, Lucas Secon, Matthew Gerrard, Kevin Rudolf, Edwin "Lil Eddie" Serrano, Jeremy Skaller, Robert Larow, Stuart Grekin, Chris Rojas, Tray J, The Messengers, Eric Sanicola, S*A*M, Sluggo, Timothy Foxx, Jordan Delani. While working on the album, the band released many of the songs as promotional singles onto iTunes, as well as debuted them on their television series. This provided great promotion for the band's music, and led to three hit songs, "Halfway There", "Boyfriend", "Big Night", to begin charting on the Billboard Hot 100.

As seen on their television series, the band worked with many well known celebrities, such as Jordin Sparks, who recorded a song with the boys titled "Count On You". When asked about the collaboration, James stated

Jordin is an unbelievable singer. If you hear her sing in real life, she sounds just as good live every time. She absolutely deserves to be where she is. She's so talented, and she's a sweetheart too. We're on the same label. She wanted to get into acting, so we wrote an episode about her. She came on and was a great actress. The song is one of our first group ballads. It's a five-way ballad, but it turned out pretty cool. Usually, a duet has one person on each side. This has her voice one side and then there are our four voices on the other [Laughs]. It worked out though. It was such a pleasure to have Jordin on the song. She became a good friend of mine. She took me to the actual show before she was in it last time [Laughs]. She's so down-to-earth like that.[3]

On September 1, the album track listing for the standard version was released online. Most of the band's songs featured on the TV Show were included on the album, which also served as the soundtrack to the First Season and part of the Second Season of the series. The songs "Any Kind of Guy", and "Famous", the latter of which is a cover of the Play song, were included on the international release of the album, along with the songs "This Is Our Someday", and "Stuck" (the last one exclusively to the UK and in some iTunes stores around the world). The previously recorded track which featured Jordin Sparks was listed on the album, along with another duet with R&B artist Cymphonique.

The second track on the album, "Boyfriend", was originally recorded and released as a solo song; however, upon being released as a single, two new versions of the song leaked onto the internet. The first version featured rapper Snoop Dogg, who appeared in an episode of Big Time Rush with the band. The second leaked version of the song featured the same artist and rapping duo New Boyz. It was initially unknown which of the two would be released as the official single; however, a reworked version which featured Snoop Dogg served as the album's official second single and also a new edit of the song including just New Boyz as collaborating artists was released as a Digital Single on iTunes. Both official versions were later included on the international releases of the album.

The music found on the album is mainly pop oriented, as well as R&B. The music found on the album is child-appropriate, as it serves as not only their debut album, but the soundtrack to their self-titled series. Jessica Dawson of Common Sense Media said of the songs on the album, "Not since 'N Sync or the Backstreet Boys has there been a boy band making such a sudden splash in the tweenage music world. Big Time Rush is a standout, not only because of their boyish charm and good looks, but because their music is a cool blend of synth-pop, hip hop, and boy-band harmonies. "City is Ours" is already a digital hit, and "Count On You" with Jordin Sparks is a catchy collaboration about earning your place in a relationship. With a hit TV show to showcase their music and their adorable personalities, Big Time Rush won't be in a hurry out of the spotlight. Parents need to know that this boy band is making tween hearts swoon with their hit Nickelodeon TV show, Big Time Rush. In their debut album they sing about relationships, going out, and making the most of your life, but it's all clean and age-appropriate for young fans."[4]

BTR has been met with generally positive reception from critics. In his review of the album, Joey Cage praised BTR, stating "The album features eleven songs mixed from the hit TV show Big Time Rush as well as original music heard exclusively on the album. The album represents the band in an upbeat, pop, rock, and R&B way. From the party sounds of "City Is Ours", "Big Night", and "Oh Yeah" to the upbeat, love songs of “Worldwide” & “Nothing Even Matters”, there’s not a single bad song on the album. I would recommend going on iTunes or to a store a purchasing this CD, these are four extremely talented individuals who deserve your support and they won't disappoint."[6] Matt Collar of Starpulse also praised the album, stating "The self-titled debut album from the Nickelodeon boy band Big Time Rush features many of the dance-pop tunes popularized on the band's TV show of the same name. Showcasing the talents of singers Kendall Schmidt, James Maslow , Carlos Pena, Jr., and Logan Henderson, BTR is a fairly accessible listen that falls somewhere between the soulful alt-rock of OneRepublic and the electro-influenced pop of Katy Perry. These are catchy, sweet, radio and club-friendly tracks that, while aimed at "tweens," should appeal to most any fan of well-crafted dance-pop. To these ends, you get the synth-driven leadoff track "Til I Forget About You," the head-bobbin' "Boyfriend", and the yearning club anthem "Nothing Even Matters", among other highlights."[7]

Lineinasong also praised BTR, stating "The album includes hit song "Til I Forget About You" and "City Is Ours" that have been featured on the show before and immediately became hits. It also includes full versions of songs "Halfway There" and "Count On You" featuring former American Idol contestant Jordin Sparks.

To promote the album, Big Time Rush embarked on many promotional tours. Member James said of the tour, "Everybody can expect us to be playing 3–5 songs at every high school we're stopping at. Then we're going to be doing a signing. We're in between filming, and that's the crazy part. We're in the middle of the second season. It's going to a pretty fun month for us! I hope people are excited for us to come to their towns. This is going to be done by the end of the month with filming in between, but we absolutely be back on the road with a full set soon."
